  1. They're OK for getting people interested in the hobby but very soon you will want something better! The ED80 is the way to go, its a lot of telescope for the money, especially secondhand! Here is a Newton designer website for those that may still have doubts; http://stellafane.or...b/newt-web.html I had to put a 31mm minor axis diagonal in this telescope (130P) to make it work properly and thats a 25% obstruction. I doubt that the diagonal is bigger than 25mm minor axis which is the normal design goal of 20% obstruction for a visual use Newton.
  2. Very nice, I'm also waiting to complete this one. I already have the HA just need the other two components now.
  3. I don't think a person just starting out in AP with this book would need to worry about this for at least 3 to 5 years. The techniques are good enough for beginners to intermediates... Once more advanced you can find your our way forward.
  4. I think the telescope is a poor choice. Mirrors under 6 inches are generally waste of time, just my opinion before people start to jump on me. The simple fact is all mirror bases systems have a central obstruction that reduces contrast and is normally sized for visual observations. They do not provide a big enough illuminated field for ccd camera's let alone a DSLR. Unless of course you look at the Quattro from Skywatch which I believe starts at 8 inches nicely proving my point! I'm just trying to save you from the agony of trying to get a none-imaging system working with a DSLR. In the end y
  5. Very nice capture, the more subs you get the less the noise will become...
  6. Very nice shot... I agree focus is critical with these lenses... good luck.
  7. Nice start but you need to get to the bottom of whats causing that gradient??? I'd expect a much stronger signal for 900s with an 314L, good luck.
  8. You need to be able to increase to gain or sensativity of the camera manually to get better results, but you have Jupiter and what looks like Ganymede captured in your image.
  9. Great shot, a pity the conditions didnt allow you to capture more detail. The colours look good to me.
  10. Excellent work, I prefer the last image since it show a bit more detail. With the two larger images it appears to me that you loose a little bit of contrast? But thats being picky since there all great captures.
  11. WAKARIMASHITA (I understand). Subaru is the Japanese name for the seven sisters or Pleiades... very nice capture, looking forward to its completion.
  12. Excellent work, beautiful image and as Peter already said, the star colours are perfect... I'll have to take a look at Theli!!!
  13. Focus is just a tad off but otherwise its a good start...
  14. Your well on your way with M1 the Crab, well done... I need to wait a little long for it to come around more.
  15. Truly fantastic... Its mind-boggling to consider just how many stars there are and the distances between them are enormous!!!
  16. Thats very nice... well done. One question though, where are your telescopes? Do you have two systems? One in Arizona and the other in Germany?
  17. That's really boring!!! NOT... Fantastic image as usual Olly. Nice to see the BabyQ is doing the job.
  18. Side note 3a; Where DSLR are concerned, Canon is king, sorry Nikon users! Try to get one with live-view because it will simplify your focusing routine which is critical..! And when possible also a 14bit A/D in RAW mode. All the brighter Nebula and Galaxies will respond well to a DSLR so your not going to be stuck for targets by choosing this route... Its also a lot easier to use a DSLR than a dedicated ccd with filters and filter-wheel + controlling software, not to mention all of the cables... There are also new techniques now for debayering the data into the RED, GREEN and BLUE channels so t
  19. But a lot of effort for 12mins, had I known I wouldn't have bothered but I'm an eternal optimist so thought it would clear!!!
  20. A better book is "The New CCD Astronomy" by Ron Wodashi, but I'll sum it up for you briefly here; 1, Highest priority is the mount, you must get a good performing solid mount, otherwise all your other purchases will be for nothing! People are recommending the HEQ5 but I would push you towards an EQ6 since it has a higher payload and is more future proof than the HEQ5. Trust me, once you start building your imaging kit the weight will go up and up and up; therefore you need the extra capacity. 2. Buy a refractor with a focal length of 500 to 1000mm. No collimation issues and no frustration guid
  21. Very nice, they look like something for me to have a go at time and weather permitting, well done.
  22. Last night I set everything up ready and expecting a full nights imaging. Unfortunately the weather gods intervened and in the end limited my testing to just 30mins of which I managed to gather 12mins of good data...! The weather conditions were horrible, intermittent clouds with the thin wispy stuff in between etc... Normally I wouldn't have set everything up but it was promising to be clear??? In the end it ever happend. So here is the first successful test at F10 with the new Mewlon (with corrector baffle assembly) I still have some minor guiding issues but I'm very pleased with the resul
  23. Fantastic images of Jupiter but your pushing it are you? C14 on top of a HEQ5!!! You might end up killing it, be careful...
  24. Wow. That was mushy too say the least!!! Will give AS!2 a try soon?
